The Fastest Shark in the Ocean
The shortfin mako shark swims at speeds up to 60 mph.
From the South Australian Research and Development Institute, with maps there, yesterday:
Jennifer is a juvenile female shortfin mako. She was satellite tagged from FV Home Strait off Lakes Entrance, eastern Victoria in mid July 2013. She was 180 cm in length. We used a very small and light SIRTRACK K2F161A satellite tag. Her tag is duty cycled at 2 days to conserve battery power.
